Linear models statistics
NettetLinear Models in Statistics is highly suitable for a theoretical statistics course for advanced undergraduate math majors, beginning math graduate students or others interested in using the book for independent study.” (Susan D’Agostino, The … NettetAbstract. In the paper the problem of nonlinear unbiased estimation of expectation in linear models is considered. The considerations are restricted to linear plus quadratic estimators with quadratic parts invariant under a group of translations. The one way classification model is considered in detail, for which an explicit formula for the ...

This module allows estimation by ordinary least squares (OLS), weighted least squares (WLS), generalized least squares (GLS), and feasible generalized least squares with autocorrelated AR (p) errors.
NettetA linear model is usually described by two parameters: the slope, often called the growth factor or rate of change, and the y y -intercept, often called the initial value. Given the slope m m and the y y -intercept b, b, … NettetNetwork-Based R-statistics for linear models. This vignette documents the implementation of NBR 0.1.3 for linear models.
